So it sounds like all we have to do is teach AC_PROG_CXX to decide if this is the Sun C++ compiler, and if so, use -g0 instead of -g. But I don't have quick access to the Sun compiler, to write a reliable test for deciding between the two ideas, so I'm relying on some help on that front. -- Don't work too hard, make some time for fun as well!
